Description
Technical field
The utility model is related to a kind of fuse, and in particular to a kind of lightning arrest fuse switch.
Background technology
Fuse switch be in power system overload and short trouble protection equipment, when electric current exceed set-point it is certain
After time, with the heat that itself is produced, make Melt molten and cut-off the switching device of circuit.At present, electrical network 10KV overhead transmission lines
In used cooperatively with fuse switch using metal oxide arrester mostly, although metal oxide arrester can play anti-
The only effect of lightning surge.But still have the disadvantage that：1st, installation cost had both been increased, had enhanced the working strength of workman,
Simultaneously excessive power equipment increased the fault rate of power circuit.2nd, arrester not only bears for a long time power-frequency voltage effect, together
When also to bear the effect of lightning surge and power frequency continued flow off and on, easily aging, its failure is a lot, and cost is very high.
The content of the invention
The purpose of this utility model is to provide a kind of protection feature good, easy for installation, non-maintaining lightning arrest drop type
Fuse.
It is described to reach above-mentioned purpose, lightning arrest fuse switch of the present utility model, including insulator and cartridge fuse
Insulator below be provided with lower metallic support, lower connecting terminal and hinge, one end of hinge are provided with lower metallic support
It is connected with cartridge fuse, the lower end of cartridge fuse is provided with full copper pipe set, and upper end is provided with operation ring and arc extinguishing hook, described insulation
The side that the middle setting of son has installing plate, installing plate is provided with ground terminal, and the top interior insulator of installing plate is provided with
Metal oxide arrester, metal oxide arrester Jing holddown springs are connected with upper metallic support, and upper metallic support is arranged
There is upper connecting terminal, rain cover is provided with upper connecting terminal.
In above-mentioned technical proposal, due to being provided with installing plate, the side of installing plate by the middle upper part in insulator
Ground terminal is provided with, metal oxide arrester, metal oxide arrester Jing holddown springs are provided with above installing plate
It is connected with upper metallic support, upper metallic support is provided with upper connecting terminal, rain cover is provided with upper connecting terminal.Take
After stating structure, upper metallic support is connected with metal oxide arrester by holddown spring, it is ensured that effective contact；Metal oxide
Arrester lower end is connected with installing plate, and reliable ground；Rain cover is provided with upper connecting terminal, rainwater and dirt can be effectively prevented
The erosion of dirty thing.
The utility model by insulator and the ingenious combination of metal oxide arrester, i.e., on the porcelain insulating pillar of insulator
The sealing of half end adds metal oxide arrester, while the use function of not shadow insulator, can also play lightning-arrest effect,
Reduce the input of operating cost；Meanwhile, can also mitigate the labour intensity of installer, and can effectively prevent power circuit from meeting with
The loss be struck by lightning causes great personal injury accident, and the great economic reparation for thus causing.
Description of the drawings
Fig. 1 is lightning arrest fuse switch structural representation of the present utility model.
Specific embodiment
This is described in further detail with new lightning arrest fuse switch below in conjunction with the accompanying drawings.
As seen from Figure 1, lightning arrest fuse switch of the present utility model, including insulator 1 and cartridge fuse 2, it is described
The lower section of insulator 1 is provided with lower metallic support 3, and lower connecting terminal 4 and hinge 5 are provided with lower metallic support 3, hinge 5
One end is connected with cartridge fuse 2, and the lower end of cartridge fuse 2 is provided with full copper pipe set 6, and upper end is provided with operation ring 7 and arc extinguishing hook 8,
The side that the middle setting of described insulator 1 has installing plate 9, installing plate 9 is provided with ground terminal 10, the top of installing plate 9
Metal oxide arrester 11 is provided with, the Jing holddown springs 12 of metal oxide arrester 11 are connected with upper metallic support 3 ',
Upper metallic support 3 ' has been provided with upper connecting terminal 4 ', and rain cover 13 is provided with upper connecting terminal 4 '.
The utility model by fuse function and the ingenious combination of metal oxide arrester function, i.e., in the porcelain of insulator 1
The sealing of insulation column upper half end adds metal oxide arrester 11, while the use function of insulator 1 is not affected, also can
Lightning-arrest effect is played, the input of operating cost is reduced；Meanwhile, can also mitigate the labour intensity of installer, and can have
Effect prevents the loss or cause great personal injury accident that power circuit is struck by lightning, and the great economic for thus causing from paying for
Repay.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of without departing from the utility model spirit and scope, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.
